METiIonoF TABLRTOP CONSTRUCTION. v

Original application filed March 2 4. 1925,'Serial No. 16,304.Dividedand this application led september 1s, 1925. rserial No. 56,628.v

Thisinveution relates to a table top construction andy is morepartici'ilarly'directed to the method of construfiftu)ny :wherein'fanartilicial stone moulding is cast to a slab and a silencing padissecured to said slab inside of said moulding.

This is a divisional application, the sub j ect matter being originallycontained in my copending application Serial No.f16,304, filed March.24, 1925. In this prior application the silencingpad was first securedto the slab Aand the moulding cast therearound, while in thisapplication the moulding is. first secured to the slaby and then thesilencing pad is secured to the.

slab inside of said moulding.

Fig. 1 is a perspective view of the table to i iFig. 2 is a sectiontaken on the line 2 2 of Fig. 1.

Fig. 3 is a vertical section through a mould showing the process ofcasting the moulding to the table top.

Fig. 11 is a sectionalview of the top slab construction showing thesilencing pad about to be fitted yinto the `recess inside of saidmoulding. f f

Fig. 5 is a partial plan view of a modified form of construction inwhich the silencing pad is composed of a plurality of small sectionsfitted together.

Fig. 6 is a detail section showing another modified form of constructionwherein the moulding is cast-united to the turned-up edges of the sheetmetal cover which is secured to the wood slab.

lThe first step in this process is to secure a sheet metal cover abymeans of screws 0. or other suitable fastening devices to a slabpreferably composed of some fibrous material such as wood, so as to belight in weight but yet possessing great tensile strength. This slab,with the metal coverA secured thereto, is then inserted into a mould d,the brackets e centering said slab in the mould in spaced relation withrespect to the side walls of the mould Large headed nails or screws fmay be secured to the edge vof the vwood slab. An artificial stonemixture is now poured into the space between the slab and mould and Ipreferably use for this, an artificial stone such as oXychloride cement.When this stone mixture iis allowed lto set the heads of.v said screwsj' are imbeddedv in the stone, thereby forming a mouldingg which issecured or cast-united to the peripheral edgeof 'the slab. yThe mould 1sarranged/in such a way as to form a moulding which overlaps slightly theperecess It.` Observing Fig; 1 it will be seen how the bottom of thisrecess'is formed of the slabi the metal cover a onthe facev of' `padelis iittedfinsaidv recess itwis quite likely' ripheral edge of said slaband provides a that seme moisture might leak past the jointv betweentheipad and moulding.;

Fig. 4: shows 'one large silencing pad fitted intothe recess butobviously thls silencing pad could be formed of a plurality of sectionssuch kas is shown in Fig. 5. Also if preferred, the edges of the metalcover a 'could be turned up asat 7c (see Fig. 6), the

turned up edges bentback and being perforated as at mit so desired. Nowwhen the stone moulding is cast about the slab this stone will flowthrough the perforations `and the moulding will be cast-united to themetal cover thus insuring a more perfeet union between the moulding andthe slab. f

This silencingpad may be made by trowel-y weight, 10% kieselguhrby'weight and 40% silica by weight. added sufficient magnesium chloridein solution at 26 degrees B. specific gravity to reduce the mixture to awet paste suitable for trowelling. This trowelled-in mass forms: asilencing pad possessing practically the same qualities as .the linoleumpad.

-WhatI claimis:

1. A method of tabley top construction, which `comprises theinserting ofa slab in a mould in spaced relation withthe sides of the mould,the'casting of an artificial stone moulding about the peripheral edge ofsaid slab, and the securing of a silencing pad thereto inside of saidmoulding.

2. A method of table top construction, which comprises the inserting ofa wooden To this ldry mixture isy slab in a mouldV in spaced relationwith the sides of the mould, the casting of an artificial stone mouldingabout the peripheral edge of said slab, and the securing of a silencingslab thereto' insidefoit said moulding and forn'led of one ormore-sectioi'is of linoleun'r litted therein.

3. The method of constructing a composite. table top which comprisescasting a stone-like moulding aroulul'th'e edges and slightly over aside of a base member, and then placing a pad on .theV base memberwithinthe portions of the moulding which extend over the side of suchbase member.

4; The method ofconstrueting a composi-'te table top which comprisescasting a stone-likemoulding around the edges and slightly, over a: sideof a base member, and then splacing a pad on the base member within theoverzslappingportiions of the moulding` which has athicknesssubstantially the same as that of the 0Verlapping portions.

5.v The method of Constructing a com positevtablertop which comprisesplacing` a basefor the topin a mould, casting a stone likemouldingaround the edges of the base member and slightly overa-side thereof,.and

then placing a pad on thev side of:V the memplate which has a part Whichextends in.

spaced relation to the edges of the base member, east-lng a stone-l1kemoulding around thev edges of the base member which coversboth sides ofthe extending part of the metallic member and Which 1s reeniorcedthere'- by, and then inserting a pad againstA the` .metallic protectingmember and Withinvthe moulding.

,In testimony whereof I aflix my signature..
